Abstract
A crack analysis device includes a captured image acquiring unit, a crack detecting unit, and a crack ratio calculator. The captured image acquiring unit acquires a captured image which is obtained by imaging a road surface. The crack detecting unit detects cracks in the imaged road surface on the basis of the captured image. The crack ratio calculator calculates a crack ratio indicating a ratio of an area of the cracks to a predetermined area on the basis of the detected cracks.
